Math tricks that make counting easier. I wonder why they don’t teach them in schools?

Mathematics isn’t the easiest subject in school. Many students have problems with high-speed counting and solving tasks. Homework is for a large group of children a real chore, and the lessons on this subject are the most boring and least understandable.

It turns out that there are some clever ways to make counting easier and more pleasant. See, what we’re talking about.

1. Multiplying by 9 has never been easier!


2. You can use the “butterfly method” to add and subtract fractions. See how simple it is!


3. This is a clever method you can use to calculate the day of the week. As a result, we know that July 30, 2069 will be Saturday (the sixth day of the week).
